Portraits?

I finished putting together a grouping of three paintings that I will put encaustic on later. Hopefully tomorrow. Now I am considering starting some portraits. I like doing lots of different types of paintings but I feel I need to narrow my scope down some. I have had good feedback on my portraits I have done from antique photos. Oh to have a little focus. Sometimes I think I have ADD! Attention Deficit Disorder! Are all artists like this or just me?
